Identify the Cause of the Grinder Clog
Before attempting repairs, observe when and how often the clog occurs. Common causes include residual coffee oils, fine grounds, or some beans that are too oily or sticky. If the grinder sounds unusual or stops mid-grind, it indicates a blockage or jam. Check for visible grounds jammed in the burrs or chute.
Understanding the root cause helps determine whether a simple cleaning or more extensive maintenance is needed. Regular use of oily beans often leads to buildup; similarly, grinding very fine coffee can cause grounds to stick and clog the grinder.
Prepare Your Workspace and Machine
- Turn off and unplug your Breville Bambino Plus to ensure safety during cleaning.
- Remove the water tank and drip tray, then wipe down to prevent messes.
- Gather cleaning supplies: a cleaning brush, a soft cloth, and the appropriate cleaning tablets (see recommended products).
Make sure the grinder is cool and free of any residual coffee grounds before proceeding. This ensures safer handling and prevents damage to internal components.
Clear the Grinder Clog Step-by-Step
- Remove the bean hopper from the top of the machine carefully, avoiding spilling beans.
- Use a soft brush or a small cleaning brush to gently dislodge any grounds stuck around the burrs or in the chute.
- Inspect the burrs for any visible blockages or grounds. If found, gently remove them with the brush or a toothpick.
- If the clog persists, run a small amount of dry, uncooked rice or specialized grinder cleaning tablets (such as Breville BEC250 or the replacement tablets listed) through the grinder to absorb oils and dislodge stubborn grounds.
- Reassemble the hopper and run the grinder empty for a few seconds to clear residual debris.
Always be gentle during cleaning to avoid damaging the burrs or internal mechanisms.
Deep Cleaning and Maintenance Tips
Regularly clean your grinder using recommended cleaning tablets, like the Breville BEC250 or the replacement tablets. These help dissolve coffee oils and residues that cause clogging. Follow the manufacturer’s instructions for use, typically involving dissolving the tablets in water or running them through the grinder.
Additionally, descaling your machine periodically (every 2-3 months) with products like the Breville Charcoal Filters or the Possiave water filters can prevent mineral buildup that affects grinder performance. Keep beans dry and stored in a cool, airtight container to prevent moisture absorption.
Perform a weekly visual inspection of the burrs and chute to catch minor blockages early. Always turn off and unplug the machine before cleaning or maintenance.
Prevent Future Clogs and Keep Your Machine Running Smoothly
Adopt best practices such as using medium or coarser grind settings when possible, especially for oily beans. Avoid grinding too fine, which can increase the risk of clogs. Use high-quality, fresh beans and keep them stored properly.
Schedule regular cleaning with cleaning tablets and descaling solutions to maintain the internal components. If you notice recurring clogs, consider replacing worn burrs or seeking professional servicing.
By maintaining a regular cleaning routine and using the correct grind settings, you’ll ensure your Breville Bambino Plus continues to produce excellent espresso without interruption.
